The team used adjustable scaffolding and diagonal cable support systems to achieve exacting tolerances on the skylight’s four barrel-shaped catenary vaults, which have thicker glass panels at the edges to sustain greater loads but lighter ones at the 92-ft apexes. It also erected the canopy, a task-with Schlaich Bergermann Partner as skylight structural engineer and Seele as facade design-assist contractor-requiring 775,000 lb of steel, 2,200 glass panels and 2,936 aluminum and glass elements overall. “Skanska split the site into two-with skylight work and platform work occurring simultaneously, which was definitely a big portion of how we were able to accelerate construction.”įrom the deck, the team reinforced the megatrusses, adding 3-in.-thick steel plate box beam supports across the tops. “Skanska basically made an investment in their logistics,” says Doug Carr, Empire State Development’s executive director. Turning the old mail sorting area of the classic McKim, Mead & White-designed structure into a sky-lit hall for rail passengers epitomized the project’s central tension-carving an innovative and functional facility out of a landmarked building built for an entirely different purpose, while balancing historic preservation with modern design. Farley Post Office into a 255,000-sq-ft passenger hub, the soaring glass structure arguably also served as the project’s design and construction highlight. But among many feats in transforming the 108-year-old James A. The one-acre, 92-ft-high glass canopy roof and skylight atop New York City’s Moynihan Train Hall was always going to be a centerpiece of the $1.6-billion transit center that expands capacity for the bustling Pennsylvania Station across the street in midtown Manhattan.
